for example, break an sbrk(>=4GB) on 64-bit architectures
even if the resource limit allowed it.
o Correct an off-by-one error.
o Correct a spelling error in a comment.
o Reorder an && expression so that the commonly FALSE expression
comes first.

second character represents some option taking an argument. This fixes
problem when ps(1) is invoked for examply as follows:
$ ps -Ufoobar1234
the above example results in option string being interpreted as
-U foobarp1234 - note extra `p'.

I'm sick of waiting on OpenBSD to make a number of changes anyway. If someone
else wants to take over fixing m4(1), I'll be glad to make them aware of the
existing issues.
4 u_ints but needs to be an array of 4 uint32_t's to work, at least
if unsigned ints have less than 32 bits. It should be a non-array of
1 uint128_t on 128-bit machines, especially if u_int has 128 bits.
The headers that declare uint32_t (actually __uint32_t) are intentionally
not included here since this header should only be included by other
headers.
Fixed some style bugs (space instead of tab after #ifndef and #endif).
proper parens mean that fd is always set by open(2) [in any part of C],
and so we can accurately check for it returning -1, without feeling like
we need to initialise fd to -1 in its declaration.
In other words, fix a stylistic/bogus nit.
implementations can provide a base zero ffs function if they wish.
This changes
#define RQB_FFS(mask) (ffs64(mask))
foo = RQB_FFS(mask) - 1;
to
#define RQB_FFS(mask) (ffs64(mask) - 1)
foo = RQB_FFS(mask);
On some platforms we can get the "- 1" for free, eg: those that use the
C code for ffs64().

Consequently, use vm_map_insert() and vm_map_delete(), which expect
the vm_map to be locked, instead of vm_map_find() and vm_map_remove(),
which do not.
Register the ISR early, but do not actually kick off the timer until we
see some activity. This still saves us from running the arp timers on
a system with no network cards.
- Added a mutex, kld_mtx, to protect the kernel_linker system. Note that
while ``classes'' is global (to that file), it is only read only after
SI_SUB_KLD, SI_ORDER_ANY.
- Add a SYSINIT to flip a flag that disallows class registration after
SI_SUB_KLD, SI_ORDER_ANY.

- Properly set M_ZERO when talking to the back end page allocators for
non malloc zones. This forces us to zero fill pages when they are first
brought into a cache.
- Properly handle M_ZERO in uma_zalloc_internal. This fixes a problem where
per cpu buckets weren't always getting zeroed.
expansion of embedded variables in the left-hand-side of an assignment
expression, using the simplest case - hiding recursion using nil-expanded
variables.
seen (somewhat) in NetBSD. This catches a few extra recursion cases that
could be hidden by expanding a NIL variable causing an existing variable to
be returned (which caused infinite looping and climbing memory usage in at
least one case).
